A tooth extractor has laid out all his surgical instruments on a table, with numerous figures looking on, in a scene that is depicted with astonishing fidelity by the painter, a follower of Caravaggio and a specialist in this type of composition. Besides the diplomas or titles, perhaps fake, certifying his training, his best calling card is his experience, substantiated by a collar of teeth worn around his neck. Would-be customers carefully watch him working and wait their turn.
